Fixed ETBasicItemStyle.selectedLabelAttributes to be an empty dictionary (the nil value was causing an exception at deserialization time)
Fixed -awakeFromDeserialization and -didLoadObjectGraph when overriden to always call the superclass implementation

Fixed ETBasicItemStyle to correctly recreate its transient state in -awakeFromDeserialization

Fixed some transient multivalued properties not declared keyed.

Fixed -[ETItemTemplate supportedTypes] to never return a nil array
